2. 2 GOVST-V Beijing 2014 WHO questions European ORGANISATION for the EXPLOITATION of Meteorological Satellites (EUMETSAT). Or Who is organised?The users. (MET services) Who is exploiting the satellites? The users. EUMETSAT is doing (with partners) user-driven satellite programmes EUMETSAT is doing more and more oceanography

3. 3 GOVST-V Beijing 2014 Observational network design The fundamental and most difficult issues in discussion of observations of any kind are all related to the two questions: 1. What is one trying to observe? 2. How well does it have to be done? A consequent, but less fundamental, third question is: 3. What is the current capability and in what ways does it remain inadequate? Carl Wunsch Observational Network Design For Climate OceanObs 2009.

7. 7 WMO / CGMS : Ocean Considerations Several coordination areas are well catered for outside CGMS, in particular by CEOS Virtual Constellations Encourage the CEOS Virtual Constellations to submit papers to CGMS on relevant operational matters with appropriate recommendations to CGMS Strengthen the link to JCOMM, in particular the Cross Cutting Task team on Satellite Data Requirements. Ocean is considered explicitly in climate activities and handled by the CEOS- CGMS Joint Working Group, and the increased capabilities of the next generation GEO satellites for ocean applications will also be addressed in this context.

24. 24 Final Remarks/Thoughts Virtual constellations as a program they virtual but as missions addressing user needs they are real. GOV is Virtual Constellation for the science of Global Operational Ocean Model Suites. Let’s remember that GHRSST started as a GODAE project. User-driven ocean satellite missions => You are in the driver seat. Hence towards space agencies Less: “Great that you guys do this for us” More: “You should do this and this!” Carl Wunsch, OceanObs 2009 Less: user advice more: user requirements Support further globalisation
